Short answer:
It's quite aggressive pool. First Thought comes Kaeris to dish out pyres and injured to prep models for graves/assasinate potentially you could try to controll center location with pyres and burning Fire Golem.
Second I thought of is Rasputina to bring to control game for claim jump in the middle and potentially hold up their forces with some gamins or cheap models, however for that maybe too squishy crew.
Long answer:
Kaeris:
So we have range dmg with good potential to stack up 1-2 injured on a model to have some solid duel advantage. Get those burning on your crew for those positive flips. If opponent have some resistance crew, those burnings, blasts, shockwaves can help to bypass those a bit.
Schemes:
Claim jump
Assasinte (depending on enemy chosen master)
Deliver a message, possible with mobile characters like Carlos
Dig their graves if opponent doesn't have corpse token "eaters"
List:
Kaeris + Totem
Fire Golem (bashy tank to hold the center)
Carlos (to dish out the burnings to your crew like the totem)
Soulstone Miner (with magical training)
To consider:
Firebranded (for them heals)
Angelica Durand (long range scheme dropper)
Envy (for even more dmg, most probably overkill)
Borgmann, also a bit tanky, can soak up some dmg to hold the center, or disturb enemy lines close combat.
Rasputina:
Schemes:
Claim jump (a bit harder to hold up with Ice Golem
Deliver a message, possible with mobile characters like Ice Dancer
Hold up their forces (gamins, maybe ice dancer)
List:
Rasp + totem
Ice Golem
2x Silent One (Pillars and heals)
Blessed of december (great mobility a can survive a bit)
Soulstone Miner (with magical training)
To consider:
Envy (range dmg)
Ice Dancer (squishy but mobile)
Ice Gamins (maybe too dangerous to take into reckoning)
